It will be helpful, when there is upgrade from firmware side to add new features &amp; remove bugs if any.

When you are updating the firmware code you need to ensure that the firmware update does overwrite or use the flash pages used by the flash manager. Since the application developer needs to be aware of the flash pages used by the flash manager, the application developer needs to responsible to ensure that it does not get over written.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/113971?ContentTypeID=1Fri, 22 Dec 2017 18:08:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:34bd67dd-36a5-4683-9bcc-56c2bfc5839fvikrant8051<p>Who should preserve the provisioning data ? Means is MESH SDK automatically take care of that or will it be responsibility of embedded application developer ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/113970?ContentTypeID=1Fri, 22 Dec 2017 12:32:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:58d2badd-8d37-49ed-abee-331cadb63830David Edwin<p>The firmware update should preserve the provisioning data stored on the Flash, so it should be possible to update the device firmware and use the provisioning data stored from earlier.</p><div style="clear:both;"></div>
